Photodynamic devices for replacement of an articular head of a bone are provided. In an embodiment, a photodynamic device includes a photodynamic support member and an articular member attachable, either fixedly or removably, to the photodynamic support member and having a bearing surface. In an embodiment, the articular member includes a recess designed to receive the photodynamic support member. In an embodiment, the photodynamic support member includes an opening into which a shaft of the articular member can be inserted to attach the articular member to the photodynamic support member.

1. A system for restructuring or stabilizing a fractured or weakened head of a bone, the system comprising: a delivery catheter having an elongated shaft with a proximal end, a distal end, and a longitudinal axis therebetween, the delivery catheter having an inner void for passing at least one light sensitive liquid therethrough, and an inner lumen;an expandable member releasably engaging the distal end of the delivery catheter, the expandable member moving from a deflated state to an inflated state when the at least one light sensitive liquid is passed to the expandable member, wherein the expandable member is sufficiently designed to be at least partially placed into a space within the head of the bone, the expandable member being inflatable and deflatable to adjust a position, an angulation, an alignment or some combination thereof of the articular member;an articular member attached to the expandable member and having a bearing surface, wherein the expandable member is configured to receive the articular member; anda light conducting fiber sized to pass through the inner lumen of the delivery catheter and into the expandable member, wherein, when the light conducting fiber is in the expandable member, the light conducting fiber is able to disperse light energy to initiate hardening of the at least one light sensitive liquid within the expandable member to form a photodynamic implant. 2. The system of claim 1, wherein the articular member has a shaft and the expandable member has an opening configured to receive the shaft of the articular member. 3. The system of claim 1, wherein the expandable member is sufficiently designed to reside within a cavity of a bone and to anchor the articular member inside the cavity when formed into a photodynamic implant. 4. The system of claim 1, wherein the articular member is fixedly attached to the expandable member. 5. The system of claim 1, wherein the articular member is removably attached to the expandable member. 6. The system of claim 1, wherein the articular member has a shaft and the expandable member, when formed into the photodynamic implant, includes an opening into which the shaft of the articular member can be inserted to attach the articular member to the expandable member. 7. The system of claim 6, wherein the opening is tapered. 8. The system of claim 6, wherein the shaft is secured in the opening by a friction fit, an adhesive, or a set screw. 9. The system of claim 1, wherein the articular member has at least a portion that is cylindrical, tubular, rounded or ball-shaped. 10. The system of claim 1, wherein the articular member has an articular part, the bearing surface disposed on the articular part, and an attachment part configured to complementarily engage the expandable member.
